Expanded PTFE Sheet

Advantage:
• Gasket making convenient.
• Low requirement for the bolt pretightening force.
• High temperature resistance, long service life.
• Ideal for damaged flanges, irregular flanges, and glass-ceramic flanges.
• No pollution for fluid.　　　
• chemical corrosion resistance.
• network structure, reduce the cold flow deformation.
• Clean, from dust-free workshop.
